Creatinine levels in the blood can vary depending on age, race and body size. A creatinine level of greater than 1.2 for women and greater than 1.4 for men may be an early sign that the kidneys are not working properly. As kidney disease progresses, the level of creatinine in the blood rises.Click to see full answer. Moreover, what does a creatinine level of 1.5 mean?The serum creatinine is a common blood test that gives us an estimate of kidney function. A very muscular person is allowed to have a higher normal creatinine compared with the average individual. A 1.8 is generally high for even a very muscular athlete. A 1.3 to 1.5 would not be for many patients.Beside above, what level of creatinine is dangerous? People with only one kidney may have a normal creatinine level of about 1.8 or 1.9. Creatinine levels of 2.0 or more in infants and 5.0 or more in adults may indicate severe kidney damage. Subsequently, question is, what level of creatinine indicates kidney failure? Creatinine levels that reach 2.0 or more in babies and 5.0 or more in adults may indicate severe kidney impairment. The need for a dialysis machine to remove wastes from the blood is based upon several considerations including the BUN, creatinine level, the potassium level and how much fluid the patient is retaining.What food should be avoided if creatinine is high?Cooked red meat in particular can affect creatinine. The heat from cooking causes creatine found in meat to produce creatinine. People with diets very high in red meat or other protein sources, including dairy products, may have higher creatinine levels than people who eat less of those foods.
